Makes connections into/or out of the gateway node, connect directly to the associated networks on the opposite side of the tunnel When done, none of the pins on the gateway node will be connected to anything. Requires both this gateway node and it's associated node to be in the same graph already (post-merging)
Returns TRUE if successful
